// QA-only Netlify Function that always returns a real HTTP 403
// Forbidden with a minimal HTML body. Used to test Prerender's
// handling of 4xx responses on a clean, page-looking URL. Reached
// publicly via /qa-403 (see redirect in netlify.toml).
//
// The 403 status code and Content-Type are set by THIS function and
// passed through unchanged by Netlify's status=200 rewrite proxy —
// the client sees a real 403, not a 200 carrying error text.
